Thinkpad 电池设置 (Ubuntu)

1. 安装下面的包：

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo apt-get install tp-smapi-dkms acpi-call-tools

2.执行

sudo gedit /etc/default/tlp

在末尾加入：

# Main battery (values in %)
START_CHARGE_THRESH_BAT0=15
STOP_CHARGE_THRESH_BAT0=100

3. 执行：

sudo tlp setcharge 

重启。

4.查看配置信息：

$ sudo tlp-stat --battery
